Anyone ever have this before

Caitlin
So many dosage changes?
I have been up and down with dose
We decreased to 50iu of puregon bc I had 6 follciles. Now I have a dominant two ar 17 but my estrogen went down ? Is this normal ?
So tonight they are increasing it up to 75 hoping that it will mature the two 17s so I can trigger?
Does this sound right? Should I be worried about the estrogen decreasing
